'1 This invention relates to handling and joining articles. It relatesmore particularly to handling and joining metal members and hasparticular utility in the fabrication of bimetallic billets. Theinvention has to do with a process of handling and joining articles andparticularly metal members and to apparatus for a like purpose.

While the invention in its broadest aspects is not limited thereto,because the invention has particular utility in the fabrication ofbimetallic billets it will be described in relation to such fabrication.Bimetallic bil-lets are employed for making bimetal in sheet or stripform, which bimetal has many uses, 'that which is at present mostimportant being the fabrication of ammunition components such as bulletjackets and cartridge cases.

For purposes of explanation and illustration I shall describe my novelprocess and apparatus in connection with the making of bimetallicbillets of steel and gilding metal. The steel may be an ordinary carbonsteel and the gilding metal may be composed of in the neighborhood of90% copper and in the neighborhood of zinc. A bimetallic billet may bemade by applying to a steel backing either one facing of gilding metalor two facings of gilding metal applied to opposite faces of the steelbacking. Whether one or two facings of gilding metal be applied to thesteel backing, it is desirable to provide the steel backing with flangesfor holding the facing or facings thereto. I shall describe theformation of a bimetallic billet by applying two opposed facings ofgildlng metal to a bac in oeseeeirifbirig understood that the'inventionin certain of its aspects is equally applicable to the making of a .7bimetallic billet in which but a single facing is desirable to deformthe flanges-inwardly againstthe respective facings to hold the i'acingstightly against the backing.

' '11 Claims. (01. 153-1) 10 the facing or facings.

2 It has heretofore been proposed to form a bimetallic billet of thegeneral type above referred to. However, difficulty has been encounteredin holding the facing or facings to the backing. I

5 have found that it is desirable in deforming the flanges of thebacking against the facing or facings to hold the facing or facings flatagainst the backing so as to prevent bowing and ingress of air and todeform the flanges while so holding I have found that this can beideally accomplished by rolling the assembled members together. Ipreferably advance the assembled members together and while advancingthem continuously pein over the flanges of the backing to hold thefacing or facings firmly in place thereagainst. Preferably while sopeining the flanges I press the facing or facings tightly against thebacking by holding rolls or roll portions. I preferably employ peiningrolls having inclined peining portions for deforming the flanges andpressing the metal of the flanges against the edges of the facings andalso having portions for pressing together the backing and facingmembers intermediate the flanges. I prefer to employ as portions of thepeining rolls resilient pressing bands which may desirably be formed ofrubber or rubber-like or other resilient material. I also prefer toemploy in connection with the peining rolls guiding and pressing rollsfor insuring proper presentation of the work to the peining rolls.

I also provide for easily assembling the billet Jiomponentsninapropercooperative relationship and advancing them to the peining rolls. Ipreferably provide means for more or less automatically positioning oneor both facings relatively to the backing and maintaining the same inproper position during advance and during the peining step. I preferablypush the work toward the pain- 40 ing rolls and provide a stop againstwhich the forward ends ofthe backing and facing members may abut .toproperly relatively position them before pushing them between thepeining rolls. I preferably provide means insuring retraction of .thestop to inoperative position when the work is pushed forward to therolls. I also preferably provide'improved means for handling the billetcomponents and inspecting the same as they approach the peining station.

The power for moving the work through the peining rolls may be appliedbythe rolls themselves or by means pushing the work through the rolls orotherwise. I prefer to drive at least one and desirably both of thepeining rolls and to employ idler guide rolls between which the workpasses on its way to the peining rolls. I preferably positively push thework forward between the idler rolls until it is engaged by the bite ofthe peining rolls when it is advanced by the driven peining roll orrolls and peined by the peining rolls, the pushing means becominginoperative as soon as the work is taken by the peining rolls. I findthat by the use of a process and apparatus of the type mentioned Iobtain highly satisfaEtory and uniform results and can fabricatebimetallic billets with great efficiency and economy.

Referring now more particularly to the drawings, there is shownapparatus for handling and joining metal members in fabrication ofbimetallic billets. Each bimetallic billet fabricated by the particularform of apparatus shown preferably comprises a steel backing memberhaving opposed flanges projecting from opposite faces thereof as shown,for example, in Figure 8, and two gilding metal facing members adaptedto lie respectively against such faces of the backing member and to beheld thereto by the flanges of the backing member. The apparatus shownis for assembling the backing member and facing members in propercooperative relationship and fastening them together.

The flanged steel backing member is designated by reference numeral 2.Thegilding metal facing member applied to the lower face of the backingmember is designated by reference numeral 3. The gilding metal facingmember applied to the upper face of the backing member is designated byreference numeral 4. The opposed lower flanges of the backing member aredesignated 5 and the opposed upper flanges of such member are designated6. The downwardly facing surface of the backing member against which thefacing member 3 lies is designated 1 and the upwardly facing surface ofthe backing member against which the facing member 4 lies is designated8. Thus the member 3 lies in a channel formed by the surface I and theinner surfaces of the flanges 5 while the member 4 lies in a channelformed by the surface 8 and the inner surfaces of the flanges 6.

Preferably the member 2 is somewhat longer elevational view of than themembers 3 and 4. Preferably eachof the flanges 5 and 6 of the backingmember are I deformed or peined over against the edges of the f facingmembers to flrmly hold the backing and facing members together and formbillet ready for rolling.

The packing members 2 are delivered to the joining apparatus by a rollertable comprising a bimetallic rollers 9 (see Figures 1, 2 and 9). Thebacking members are advanced from left to right viewing Figures 1 and 2,preferably coming directly from pickling apparatus where they arepickled and cleaned so as to be free from dirt and scale. The backingmembers are advanced by the rollers 9 until the leading ends thereofstrike against a stop ll. Usually a number of such members are advancedin substantially side by side relationship on the rollers 9 and thestopI0 is effective for accurately lining them up transversely of theapparatus as shown in Figure 1.-

The members 2 are preferablydelivered against the stop III in uprightposition as the three righthand members 2 are shown .in Figure 9. Themembers are then moved successively transversely of the direction oftheir advance on the rollers 9 and to the left viewing Figure 9 intoposition to be assembled with the facing members. The member 2 which isdisposed farthest to'the left, viewing Figure 9, on the rollers 9 ispreferably turned on its side by hand or by'a suitable toolor hook heldby a workman until it rests upontwo of its flanges as the left-handmember is shown in Figure 9. In this position the face which was towardthe right is now uppermost and may be inspected. The face which wasoriginally toward the left may be inspected either prior to turning themember as just described or after it reaches its succeeding position inwhich such face will be uppermost, as will presently appear.

There is provided a roller table comprising rollers II which is disposedbeside the roller table comprising the rollers 9 but at a lower level.The table comprising the rollers H is narrower than I are identical eachfacing member designated 3 in Figure 1 may be applied either tothe-bottom or to the top of a backing member 2. The facing members areordinarily of sufliciently light weight that one of them can be handledby one man or, in anyevent, by two men. There is provided a roller tablebest shown in plan in Figure 3 which comprises idler rollers I5, thetable comprising the rollers |5 being disposed immediately in front ofthe support It as shown in Figure l. The roller table comprising therollers i5 is also shown in elevation in Figure land in transverse crosssection in Figures 7 and 11. 'Such table is supported by a base l6 whichcarries spaced 1- beams Each I-beam I'I carries on its top opposedangles, an inner angle l8 and an outer angle 9. Each of the angles I8and I9 has one flange resting upon the upper flange of its supportingI-beam l1 and the other flange projecting upwardly. The upwardlyprojecting flanges of the angles l8 and I9 serve as supports for thethat comprising the rollers 9 and is adapted to receive and convey oneof the members 2 at a time, Disposed between the tables comprising therollers 9 and II, respectively, is a series of guide plates l2 whoseshape is shown in Figure 9. As one of the backing members 2 is slidtoward the left, viewing Figure 9, from its position resting upon twoflanges upon the rollers 9 it moves slightly upwardly as it engages theguide members l2, whereby it is removed from the rollers 9, and then ispermitted to slide down upon the curved left-hand faces of the guidemembers i2 and come to rest on the rollers I I The member 2 may turnover in settling onthe rollers so that the flanges which are uppermostwhen it lies on the rollers 9 are lowermost when it lies on the rollersII, or if this does not occur without assistance from the operator it isa simple matter for the operator to exert slight pressure on themembenas it falls upon the rollers II to insure that it wmlieflporpsuchrollers with the flanges downward which werkuppermost in flxedpositions.

roller-s15. Each roller i5 is journaled for free rotation upon a pin 20.The upwardly projecting flanges of the angles J8 and |9 are slotted. at2| as shown in Figure 4, the slots being in transversely aligned pairs.Eachof the pins 20 has vertical slots22 in its side faces so that whenit is introduced into a pair of transversely aligned slots 2| in theangles it will be held by interengagement of the edges of the slots 2|and 22. Thus ,the rollers l5 are mounted on the pins 20 Each of therollers l5 has a portion 23 of relatively small diameter and a portion24 of relatively great diameter, an annular shoulder 25 being formedtherebetween. As will presently be seen, the shoulders 25 of the rollersI5 cooperatively perform a guiding function with respect to the work.

Connected with the inner face of the upwardly projecting flange of eachof the angles l8 is'a plate 29. The upwardly projecting flange of each-of the angles i8 is provided at intervals with vertically elongatedslots 21.

through each plate 26 and through the respective slots 21 in the angleby which the plate is carried and nuts 29 are applied to the screws andscrewed up against the outer face of the angle flange. Thus the plates26 are held to the angles and may be vertically adjusted by reason ofthe vertical elongation of the slots 21. The plates 26 are at any giventime arranged with their upper surfaces at the same elevation for apurpose which will presently appear. The plates 26 also have verticallyelongated slots 26a (see Figure 4) wider than the slots 2| and intransverse alignment therewith to provide space for the ends of the pins20.

Carried by the angles l9 and projecting upwardly therefrom are members30 carrying inwardly projecting guides 3| as shown in Figure 7. Theinner faces of the guides 3| are spaced when it lay upon the rollers 9.Thus am ple-op:

portunity for inspection of all portions of each of the members -2 isafforded from the time such members are delivered against the stop l0until each of them is conveyed away upon the rolls II as will now bedescribed. A guide l3 cooperates with the members |2 to maintain on therollers II the member 2 delivered thereto as just described.

There is provided a support It for facing members which are designatedby reference numeral 3 in Figure 1. Since-the facing members 3 andslightly outwardly from the vertical planes containing the shoulders 25of the opposed rows of --rollers IS.

The shoulders 25 of the opposed rows oilers l5 are spaced apart adistance substantiallyequal to or very slightly greater than thedistance between the outer faces of opposed flanges of thev members 2 asshown in Figure 7.

The upper surfaces of the plates 26 are disposed at an elevationslightly higher than the tops of the roller portions 23 as shown inFigure 7. The plates 26 are adapted to support facing v members 3 asshown in Figure 7 and as will presently be described.

Screws 28 pass ing angles 32 (Figures '1, a and 11) forming a track fora carriage designated generally by reference numeral 33 (see Figures 2and 4). The

carriage 33 comprises opposed side members 34 carrying axles 35 which inturn carry wheels 35 adapted to ride in the track formed by the angles32. The vertical spacing of the angles 32 is such as to allow clearancefor rotation of the wheels 36 durin movement of the carriage along thetrack but prevent substantial tilting of the carriage.

The rear axle 35 of the carriage 33 has pivoted thereto between the sidemembers 34 a pusher 31. Integral with the carriage is a stop member 38which when the pusher is in the position shown in Figure 4 preventsrotation thereof in the counterclockwise direction about the axis of therear axle 35, viewing that figure, but permits clockwise rotation of thepusher. The carriage 33 also carries a projection 39 while the pushercarries a lug 40, and a tension coil spring 4| is engaged between theprojection 39 and the lug 40 to urge the pusher back against the stopmember 38 as shown in Figure 4.

The purpose of the pusher 31, as will presently appear, is to pushthework into the bite of the peinin rolls. The pusher extends upwardlybetween the I-beams l1 and between the plates 26 so that its upperportion is adapted to lie behind work carried by the rollers l5 to pushsuch work toward the right, viewing Figures 1 t0 4, inclusive. The upperportion of the pusher may assume various shapes as presently to bedescribed or may present simply a vertical surface to push the worktoward the right. In Figure 4 the pusher is shown as having a projection42 carried by its upwardly projecting portion, the projection 42extending generally-horizontally when the pusher is in the positionshown in Figure 4 and having its upper surface lying somewhat above thelevel of the upper surfaces of the plates 26 as shown. As will Presentlyappear, the purpose of the projection 42 is to push the lower facingmember 3 along the guideway comprising the rollers l5 in predeterminedspaced relationship with respect to the backing member 2. In Figure 4-the face designated 43 of the pusher 31, which face lies above theprojection 42, is adapted to engage the backing member 2 to push italong the guideway.

In Figures 21, 22 and 23 there is shown a modified form of pusher. Inthese figures the pusher ,is designated generally by reference numeral44 and has two vertically spaced integral forward projections 45 and 45.Shoes 41 are adapted to be held against thclinner faces of theprojections 45 and 46 by bolts 48. Each shgghas a for= wardly facingshouldegjil and forwardly of the shoulder has a substantially planesurface portion 5llterminating in a curved or flaring surface portion5|. The heads of the bolts 48 are sunk within the shoes 41 as shown inFigure 21. The shoulders 49 are adapted to engage the facing members andthe face 52 of the pusher between the shoes 41 is adapted to engage thebacking member in pushing forward the assembled components of abimetallic billet. The curved portions 5| of the shoes 41 are providedsimply to insure ease of passage of the billet components into the spacebetween such shoes.

Mounted beneath the rollers 'H upon supports 53 carried by the floor 54is a fluid pressure cylinder 55 (Figures 2 and 25) containing a pistonto which is connected a piston rod 56 the outer end of which isconnected to the carriage 33 as shown in Figure 4. Means as shown inFigure 25 and presently to be described but omitted in Figure 2 for thesake of clarity are provided for admitting fluid pressure either infront of or behind the piston in the cylinder 55 to move the same to theleft or right, viewing Figure 2, as desired. Movement of the piston isaccompanied by corresponding movement of the carriage 33.

Connected with the inner face of the left-hand I-beam l1, viewing Figure11, is a pair of longitudinally spaced generally horizontally extendingstraps 51 (see also Figure 12) only one of which is shown in thedrawings since such straps are uniform in structure and function. Eachof the straps 51 serves as a guide for a positioning member 58 which ismovable generally vertically therein. Each of the two positioningmembers 58 lies against the inner face of the web of the I-beam and thecentral portion of the corresponding strap 51 forms with the inner faceof the I-beam a generally vertical guideway for the positioning member.Each positioning member 58 is provided with a vertically elongated slot59 at its upper portion as shown in Figures 10 and 12. A guide bolt 6|]passes through the upwardly projecting flange of the adjacent angle 18and the plate 26 connected therewith and through the slot 59 of each ofthe positioning members 58 to serve in conjunction with thecorresponding strap 51 to guide such positioning member for verticalmovement. The upper extremity of each of the positioning members 58 iscut out to provide an upwardly facing shoulder BI and an inwardly facingshoulder 62 as shown in Figure 10.

Each of the positioning members 58 has a cutout portion 63 into whichextends a longitudinally disposed bar 64 which is bolted to thepositioning member by a bolt 65. There is only one such bar 64 and it isthus connected with one of the positioning members 58 at one end andwith the other at the other end. At its center the bar 64 has a pair ofopposed outwardly projecting ears 66 through which passes a pin 61. Thepin 61 also passes through one end of a link 58. The other end of thelink 68 is pivoted by a pin 69 to a rocking lever 10 which is pivoted ona pin 1| carried by the left-hand I-beam l1, viewing Figure 11, in alongitudinally extending slot 12 therein (see Figure 13). The rockinglever 10 passes through the I-beam and lies within a verticallyextending slot 13 therein which intersects the longitudinally extendingslot 12. Pivoted to the outer end of the lever H1 at 14 is a generallyvertically extending link 15. Pivoted to the base [6 at 16 is a rigidL-shaped lever 11 to which the ""lower extremity of the link 15 ispivoted at 18.

The base I8 is suitably cut out to accommodate the lever 11 and thelower outside flange of the left-hand I-beam [1, viewing Figure 11, iscut out at I9 to accommodate the link 15 (see also Figure 13) Likewisethe upper inside flange of the same I-beam is out out as indicated at inFigure 12 to allow each of the positioning members 58 to passtherethrough. A treadle 8| is connected with the outer extremity of thelever 1'! as shown in Figure 11. When the treadle BI is depressed by theoperators foot the linkage shown moves the respective positioningmembers upwardly to their operative positions as shown in Figure 11 toposition a facing member 3 as will presently be described. Release ofthe treadle 8| permits the positioning members 58 to drop down toinoperative position by gravity. The mechanism just detherebetween.

assess? of cylindrical rollers 82 as shown in Figures 1 to 4, inclusive,8 and 17; The rollers 82 receive the work from the rollers i5 as itadvances toward the peining rolls. Mounted on the floor it below therolls 02 is a cylinder 89 (Figures 2, 17 and 25) arranged win its axisvertical and containing a piston to which is connected a piston rod 89.A connecting rod 80 is connected to the piston rod and is also connectedat 06 to a projection 9? of a stop pin 80 which is guidedfor generallyvertical movement in a guide sleeve 89 mounted in the frame. A tensioncoil spring 90 connected with the lower end of the stop pin 88 and witha lug 95 connected with the outside of the cylinder 89 normally pullsthe stoppin 83 downwardly.

Downward movement of such pin is limited by a stop screw 88a. mounted ina collar 8% carried by the frame and entering a slot 860 in the pin.Fluid connections 92 and 93 to the piston 83'are shown in Figures 17 and25.

The pusher 3i and the stop pin to are fluid operated from the samesource of pressure fluid.

Referring to Figure 25, the source of pressure fluid may be a pump (notshown) from which leads a pipe 94. The pipe 90 enters a'valve 95 havinga rotatable valve element controlled by a handle 95a and to which areconnected pipes 96 and 91 and an exhaust 99. The pipe 96 leads tobranches 93 and 99. The branch 93 leads to v the upper end of thecylinder 63 and the branch 99 leads tothe rear end of the cylinder 55.The pipe 9! leads to branches 92 and I00. The branch 92 leads to thelower end of the cylinder 83 and the branch I00 leads to the forward endof the cylinder 65. When the source of pressure 94 height of thebimetallic billet as it emerges from the peining rolls. The billetpasses between-the rods, the inclined face portions H0 serving toproperly guide the forward end of the billet if it should not passdirectly between the rods. The function of the rods is to prevent thebillet from twisting substantially about its longitudinal axis after therear end of the billet has left the guide rolls I03. Slight clearancefor the billet is provided between the rods I I6 so that'the billet maytwist to a-very slight or immaterial extent, but any substantialtwisting is prevented by the rods. If a tendency toward twisting existsthe corners of the billet will engage the upper and lower rodsrespectively, which will prevent substantial twisting. Rollers may, ifdesired, be substituted for the rods H6.

The form of the guide rolls I03 is shown in Fig ures 5, 1'7 and 19 andthe relation of such rolls to the work is shown in Figures 17 and 19.The form of the peining rolls I00 is shown in Figures 5, 6, 17 and 20and the relation of such rolls to the work is shown in Figures 17 and20. The guide rolls I 03 are not driven but are free to turn uponengagement with the moving work. The peining rolls I04 are driven,preferably at a speed slightly greater than the speed of advance of thepusher 31 sothat when the pusher advances the work to the point at whichthe front end thereof is gripped by the driven peining rolls such rollswill carry the work forward. relatively to the pusher and the pusherwill become inoperative.

Each of the guide rolls I03 has abroad central cylindrical face portionI06 bounded by grooves I09. Outside the grooves I09 are projectingportions I I0 which may assist in centering the work is connected withthe pipe 96 and the pipe 9'! is connected with the exhaust 38, asindicated by the arrows in Figure 25., the pusher is pushed forwardly ortoward the right and the stop pin 83 is moved downwardly by the actionof the sprin 90. When, however, the valve is turned so that :pressureenters the pipe 91 and the pipe 96 is connected with the exhaust 98 thestop pin 08 moves up and the pusher is retracted toward the left. Thefluid passing to and from the cylinder 55 is throttled through orificeplates IOI, one of which is shown in Figure 24, so that the action ofthe pusher is slow and uniform. The orifice plates IOI are inserted intopipe connections I02 leading to the cylinder 55 as shown.

In alignment with the guideway comprising the rollers II, I5 and 02 is apair of guide rolls I03 followed by the peining rolls I04. The guiderolls I03 and the peining rolls I04 are mounted in 0D- posed housingsI05 and the respective rolls I03 and the respective rolls I04 may beadjusted in usual manner to vary the height of the roll pass A runouttable I06 havin idler rollers I01 thereon receives the work as it passesforwardly from the peining rolls.

'1 preferably provide extending between the housings I05 at the faces ofthe housings nearest the runout table I06 two rods II6 spaced one abovethe other as shown in Figures 2 and 6. These rods are bolted to therespective housings by bolts I I1. They preferably have inclined centralface portions II8 as shown in, Figure 2, the

upper of which is inclined toward the peining rolls and upwardly and thelower of which is inclined toward the peining rolls and downward1y.,

The vertical distance between the rods H6 is preferably slightly greaterthan the maximum to the guide rolls as it enters between such rolls fromthe roller table guideway.- The function of the facings 3 and 4 andpress the same firmly I against the backing 2. However, the guide rollsI03 do not exert sufficient pressure to in any way deform the workexcept possibly to smooth out slight bends or warpage in the facingmembers.

The flanges of the backing member 2' project slightly into the groovesI09 of the guide rolls I03 and have ample clearance therein as shown inFigure 10. If, however, the work tends to skew oif toward one side orthe other the flanges .will engage with the inner edges of the roll faceportions IIO to keep it in proper alignment.

The peining function is accomplished entirely by the peining rolls I04.These rolls are shown in cross section in'Figure 20 and the work 'isshown as being engaged and peined thereby. Each peining roll has areduced central face portion III and projecting face portions II 2 onopposite sides thereof. Inclined operative or peining face portions I I3extend between the face portions I I I and H2. The portions H2 and H3intersect at corners A. The transverse distance between the flanges.This is shown in Figure 20. The inclined roll face portions II3consequently are brought into engagement with the flanges 5 and 6 of themember 2 and deform or pein such flanges inwardly and slightlydownwardly to engage the 7 edges of the facing members 2 and 3 as showninFigure 20.

Bands of rubber or rubber-like material II4 are preferably, although notalways necessarily, applied to the recessed face portions II of thepeining rolls I84 as shown. in Figure 20. The bands H4 to all intentsand purposes form integral parts of the respective peining rolls I04 butare relatively resilient since the other portions of the peining rollsare of metal. The thickness of the bands I I4 is such that when thepeinlng rolls'are adjusted as above described the vertical distancebetween the opposed faces of the bands in the vertical center line ofthe peining mill is somewhat less than the thickness of the assembledbillet components from the outer surface of the upper facing member tothe outer surface of the lower facing member. Depending on theresilience of the rubber or other relatively resilient material used forthe bands I I4, the distance between their opposed faces will be greateror less, but such distance when no work is being acted upon by thepeining rolls may be approximately equal to the thickness of the bodyportion of the member 2, that is, the vertical distance between thefaces I and 8 thereof. Thus when the assembled billet components enterthe peining rolls as shown in Figures 1'1 and the bands aresubstantially compressed and exert consid erable, although yielding,pressure upon the facings 3 and 4 to press and hold them in positionagainst the backing 2. It is desirable that the facings be held firmlyagainst the backing while the peining action is taking place. The bandsI I4 cooperate with the guide rolls I84 to straighten out slight bendsor Warpage in the facing members 3 and 4 and insure that they lie flatand smooth against the respective surfaces 1 and 8 of the member 2.

I shall now describe one mode of operation of the apparatus describedabove and one method of handling and joining components of a bimetallicbillet. A number of backing members 2 are advanced on the rollers 9 fromleft to right, viewing Figure 1, until they strike the stop I8. At thetime of their advance such members 2 are standing on end as are thethree right-hand members 2 shown in Figure 9. An operator turns down themember 2 nearest the rolls I I as shown in Figure 9 and then slides suchmember over the guide members I2 until it falls upon the rollers II. Byexercising a little care in manipulation the member 2 can be caused tocome to rest on the rolls II with the flanges which were in engagementwith the rollers 8, as shown in the case of the left-hand member 2 inFigure 9, projecting upwardly away from the rollers I I. Thus the entiremember may be inspected between the time it enters on the rollers 9 andthe time it is advanced on the rollers II.

When the member 2 falls on the rollers II it is substantially centeredthereon by the guide members I2 and the guide I3. At about the same timeanother operator takes one of the facing members 3 from the support l4(see Figure 1) and places the same so as to rest on the upperextremities of the plates 26 and with its for- 12 ing thereoftransversely of the guideway. The

' upwardly projecting positioning members cooperatively furnish a guideagainst which the lefthand edge of the facing member may be positionedas shown in Figure 11, the facing member being moved against thepositioning members by hand. The treadle 8| is then released and thepositioning members 58 move down to inoperative position, leaving thefacing member properly aligned and centered on the tops of the plates26.

With the member 2 disposed on the rollers II as above described and thefacing member 3 positioned on the tops of the plates 26 as justdescribed the respective members 2 and 3 are in substantial longitudinalalignment but with the upper surface of the member 3 very slightly below the level of the surface I of the member 2. The rollers l I are thenrotated to move the member 2 toward the right viewing Figures 1 and 2,orthe member 2 may be pushed along by hand, in which case the rollers IImay be idler rollers. In either event the member 2 moves toward theright relatively, to the positioned member 3. As the member 2 thus movestoward the right, viewing Figures 1 and 2, it runs into the left handface of the upper extremity of the pusher 31 which is disposed in itspath. The movement of the memward end in contact with the stop pin 88which at such time is in raised or operative position. This operatordepresses the treadle 8I which raises the positioning members 58 to theposition shown in Figure 11. The purpose of these positioning members isto'insure proper alignment of the facing member and also properpositionber 2'forces the pusher 31 to turn in the clock wise directionabout the axis 35 so that the pusher moves forwardly and' downwardly outof the path of the member 2 which thereupon advances over top of thepusher until the end of the mem ber 2 has cleared the pusher, whereuponthe spring 4I returns the pusher to the position In which it is shown inFigures 2 and 4 ready to push the work forward.

As above mentioned, at the time the facing member 3 is positioned on theplates 26 as above described the stop pin 88 is in its upper oroperative position in which it extends in the path of the work and theforward or right-hand end of the facing member 3 is positioned againstthe pin 88. When the member 2 is advanced as just described it movesforward until its forward end engages the pin 88. As the member 2 movesforward it rides on the face portions 23 of the rollers I5, theshoulders 25 positively guiding the member 2 and maintaining it in astraight line, as indicated in Figure '7. The plates 26 are adjusted tosuch a height that the facing member 3 is held approximately in contactwith the member 2 as it thus advances so that the member 2 straddles themember 3 as shown in Figure '7 and moves forward while the member 3remains stationary. The member 3 cannot advance due to any contactbetween it and the member 2 because such advance of the member 3 isprevented by the pin 88. The member 2 advances while straddling themember 3 until both of such members are in stationary position withtheir front ends abutting against the pin 88. At such time the operatortakes another of the facing members from the support I4 and places thesame on top of the member 2 between the flanges 6 and also with itsfront end engaging the pin 88. The thus assembled billet components arethen ready to be advanced between the guiding and peining rolls.

When the pin 88 is up the piston in the cylinder 55 is toward the leftviewing Figure 25 as hereinbefore explained. When the billet componentsare assembled as above explained with their forward ends against the pin88 the valve is turned to the position illustrated in Figure 25whereupon the pin 88 is retracted downwardly out of the path of the workand the pusher 31 is moved forward.

' 23 The forward extremity H of the projection 82 engages the rear endof the lower facin member 3 while the surface 43 of the pusher engagesthe rear end of the member 2.

form shown in Figures 21, 22 and 23 is employed it is not essential touse the pin 88 as the pusher automatically determines the relativelongitudinal positions of the members 2 and 3 and it is not diflicult toplace the upper facing member d on the backing member 2 in a positioncorre-' sponding to that of the lower facing member 3.

It is possible in some circumstances to dispense with the projection 42of the pusher 31 and employ a pusher having a smooth work engaging facewithout any projection. Thismay be done when the friction between themembers 2 and 8 is greater than the friction tending to hold the member3 against forward movement with the member 2. In such case pressure uponthe rear The member 2 is preferably longer than the member 3 by a disendof the member 2 will cause the assembled components to move forward toether.

The form of pusher shown in Figures 21, 22 and 23 is designed topositively insure under any circumstances proper relative positioning ofthe members 2, 3 and 4 as they are advanced to the peining rolls. Themember 2 is engaged by the surface portion 52 and'the members 3 and lare respectively engaged by the lower and upper shoulders 49. The formof pusher shown in Figures 21, 22 and 23 is designed for use withfacingmembers which are somewhat greater in length relatively to the backingmember than is the case with respect to the facing members for use withwhich the pusher 31 is designed.

The pusher advances the work between the guide rolls I I13 and thepeining rolls I04 which cooperate therewith as above described to guideand work upon the assembled components andto pein down the flanges ofthe backing member 2 against the edges of the facing members 3 and 4 asshown in Figure 20. The thus fabricated billet is delivered from thepeining rolls upon the table I06 whence it may betaken to the rollingmill for rolling into bimetallic strip.
